Thinkpad Battery Status Reporting: Created by
Braindamaged Monkeys
The IBM/Lenovo Thinkpad battery firmware is bad. Very, very bad. It
attempts to use a power flow integration or "Coulomb counting"
approach, and manages to get it very wrong, producing far worse
results than could have been had simply by using the battery voltage,
and becoming more wrong with each charge/discharge cycle, eventually
thinking the battery is empty when it's about 50% charged.
"Braindamaged", really, is too kind a word to properly describe my
opinion of the "engineers" who created this system. I'll elaborate.
